Re: JNDI Properties? Why EJB can't find another EJB..
why don't you post a minimalistic example with your ejb-jar.xml and

stupid/no_offense as we've never had those problems in more than a year

Re: Now how do I explain this? One entity bean, multiple data sources perhaps...

A "dev", "test", "stage" and snip/ in short: what you really want is not possible. you cannot dynamically associate a cmp entity with a datasource. I know the problem with the dev, staging, test etc. environments and your best bet IMHO is to simply deploy the entire application once for each datasource which is really just copying your deployment directory structure. one more thing that comes in handy here is the datasource-alias feature (undocumented) which allows you to map a datasource name to another one (yet another level of indirection) thereby giving you the possibility to change the datasource of your app with only one change in the deployment files (i.e. in the application local data-sources.xml). taken from an application local data-sources.xml file: data-source class="com.evermind.sql.AliasDataSource" location="jdbc/ShopEJBDS" source-location="jdbc/ProcurementRefEJBDS" / /data-sources the fact that you find your default datasource in orion-ejb-jar.xml upon first deployment is not a bug. you can redefine the default datasource for that app and it will be put there (and by definition doesn't have anything to do with what you do to ejb-jar.xml). you'll do yourself a favour if you keep reading up on this stuff as some of your comments indicate that you haven't entirely understood the separation of the different roles (manifested in the responsibilities of the different config files) in J2EE (which is not surprising after only 4 weeks of getting to know J2EE). A good starting point will be the commented dtds of orion with the spec(s) at hand. this is absolutely crucial to being able to get the maximum out of the flexibility of J2EE (and orion) deployment. something many people don't seem to know is, what's defined by the spec and what's left to the J2EE vendor. hope this helps somewhat, robert Each time you deploy. I **MUST** be doing something wrong here. This can't be right. Has anybody done anything similar in the past? I've read just about every damn book on this and scoured the web to no avail. Either I'm as dim as a box full of broken light globes, or I'm in overload (I didn't know J2EE from a bar of soap 4 weeks ago), or I'm not getting something fundamental that everybody else seems to take a-priori.

SV: JNDI Properties? Why EJB can't find another EJB..
A
possible problem is that you have forgot to add ejb-refs for the beans you wish
to use from your bean on your bean in the deployment descriptor (ejb-jar.xml) in

Orion-specific descriptors authentication API
I have some questions regarding these Orion-specific deployment descriptors that I can't seem to find much information on. It would be great if someone can give me some pointers. In doing CMP entity beans, somewhere one must bind the bean to a data source. Apparently this is in orion-ejb-jar.xml and orion-application.xml. Where do these files go? Do they sit along-side the standard descriptors in the JAR files (e.g. orion-ejb-jar.xml and ejb-jar.xml go together in the abc-ejb.jar file) ? If not, where? How can they be maintained as part of the source code? How do I tell Orion that I am using PostgreSQL as my database for entity beans? data-sources.xml doesn't seem to "ell Orion what type of database a data source is. How do I access the user authentication mechanism? There are "security adapters" in the J2EE reference implementation. The Orion API has a bunch of *Manager and *UserManager classes, but the documentation is very vague. Are these it? How do I use them? Lastly ... are there examples for any of these? An example is sometimes worth a thousand words.

Problems with update
Hi! I have a simple J2EE application running on Orion. In short I have a entity-bean wrapping a table in a data base, and a session-bean reading from this entity bean. On "top" i have a JSP-page connecting to the session-bean and presenting the contents of a field in the database. So far, so good. The problem is that when I update the contens in the database (manually), the JSP page, and the session and entity bean still contains the "old" information. Not unless I restart Orion the contens is beeing updated. It seems to me that the entity-bean is beeing cached in Orion, and not beeing refreshed when the table it is wrapping is beeing altered. Have anybody experienced a similar problem, and does anyone have a solution??? Knut

Erm.. To clarify the need for four environments...
Hiya, Thanks to the replies. Ta Christophe and Robert! There seems to be some confusion as to why there are four environments in my last post regarding the datasources. To short-circuit any more "Why the hell are you doing it that way?" questions, I will provide a little bit of background. I have a desktop (Obvious really). So do the suits who work in my section (Again obvious). My group is but one of many groups. Our DEV environment is mine, all mine. Heh heh. The test environment is exactly that. A place where our section deploys just our stuff for testing. Then there's staging. That's where my section deploys and a whole bunch of other sections deploy their stuff for testing to make sure there are no interdependency issues. Then we have production (what the punters see). Luckily our section have our own private servers there, so interdependencies don't occur. The rest of the company uses COM/COM+/VB/ASP etc which is why they need to test those things. And I'm trying to convince my suits to go J2EE. But I'm stuck with an ASP/VB/COM site at present. My suits need to get valid info from the production environment. Then they like to test new ideas and what not on Dev. Then on Test. Then on Stage. So they want 1 (one) interface that allows them to try stuff out on each of the environments. So I thought it would be a nice idea if they could use my "JAdmin" environment on my desktop to allow them to view pages that allow them to view tables from each of the servers. For example a single page with "top 10 products by region" for each environment. This implies a single page that can access each of the environments databases, get the data from the "product" table from each and format it. It just seemed a tad weird to have to use seperate apps to access each environment just because the datasource was different. I had originally assumed that it would be possible to have a page use a session bean that accesses entity beans that get that data from each of the environments. I had not considered that this would be a problem. I was wrong. I had originally done the page using a servlet and simply accessed the data via a plain-old-bean that had a "setDatasource()" method and a "loadStatistics()" method. So the servlet could set the datasource of the bean to PROD, load the stats, set it to STAGE, load the stats, and so on. So thanks to everybody who replied. I need to do more reading. **Rant mode on** Unfortunately I'm in a bind. Moan moan whinge whinge. I get Monday morning to work on this.

Running multiple application instances with Orion
I've put together a how-to on running the same J2EE application, but with each instance using a different data source, using Orion. It would be nice if there was a simpler way to do this (particularly in associating data sources with applications, which causes the bulk of the work). If the orionsupport.com folks are listening, you have my permission to add this to your site (just be sure to give credit where due). Kurt in Atlanta Title: Running Multiple Application Instances with Orion Running Multiple Application Instances with Orion Kurt Hoyt ([EMAIL PROTECTED]) This document assumes you know how to create an EJB .jar file, a web application's .war file, and a J2EE application's .ear file. All this document does is describe the changes you need to make in order to run multiple instances of the same application within the same instance of Orion (one JVM running on one computer), with each instance using its own data source. The data-sources.xml file Create the data source entry in Orions config/data-sources.xml file. Here are the two data sources I created, one for SQL Server and one for Oracle: data-source class="com.evermind.sql.DriverManagerDataSource" name="SQLServer" schema="database-schemas/ms-sql.xml" location="jdbc/SQLServerCoreDS" xa-location="jdbc/xa/SQLServerXADS" ejb-location="jdbc/SQLServerDS" connection-driver="com.inet.tds.TdsDriver" username="orion" password="orion" url="jdbc:inetdae7:SQLServerHost:1433?database=orion" inactivity-timeout="30" / data-source class="com.evermind.sql.DriverManagerDataSource" name="Oracle" schema="database-schemas/oracle.xml" location="jdbc/OracleCoreDS" xa-location="jdbc/xa/OracleXADS" ejb-location=jdbc/OracleDS" connection-driver="oracle.jdbc.driver.OracleDriver" username="orion" password="orion" url="jdbc:oracle:thin:@OracleHost:1521:orionora" inactivity-timeout="30" / Notice that the ejb-locations are different between the two data sources. Each data source will need a unique ejb-location (and the other locations). Notice the naming convention: jdbc/some-nameDS for the ejb-location, jdbc/some-nameCoreDS for the location, and jdbc/xa/some-nameXADS for the xa-location (xa = transactional). There is also a pooled-location that can be used if the data source needs to be accessed from outside the EJB server (like inside a JSP). Its the ejb-location that youll need for the orion-ejb-jar.xml file. There will be a 1:1 relationship between each application instance and its data source. The orion-ejb-jar.xml file Once you have a data source set up, you have to tell Orion to use that data source for the tables it creates for the entity beans in the EJB jar file (which Ill call myapp-ejb.jar for discussion purposes). You do that by editing the orion/orion-ejb-jar.xml file that youll put inside the myapp-ejb.jar file. This means that you will have a different myapp-ejb.jar file for each application instance, with the only difference being the contents of the orion-ejb-jar.xml file. For each entity bean, you tell Orion which data source from the config/data-sources.xml file to use: entity-deployment name="Customer" table="Customer" data-source="jdbc/OracleDS" . . . /entity-deployment This is the skeleton for the Oracle version of the Content entity bean deployment. The entity-deployment tag sits inside the enterprise-beans tag inside the orion-ejb-jar tag inside the orion-ejb-jar.xml file. Notice the data-source attribute in the entity-deployment tag. Thats how the connection is made. The data-source attribute must be set for each entity bean, so each entity bean must represented with an entity-deployment tag inside the file. For SQL Server, the same skeleton looks like this: entity-deployment name="Customer" table="Customer" data-source="jdbc/SQLServerDS" . . . /entity-deployment You can see how each version uses a different data source. I saved the Oracle version in a file called oracle-orion-ejb-jar.xml and the SQL Server version in a file called sqlserver-orion-ejb-jar.xml. It should be simple to create some kind of database-neutral skeletons that could be run through some filter program that would assign the data source for you. Build the myapp-ejb.jar file To build the myapp-ejb.jar file, you need to have this directory structure somewhere: mypackage/*.class (the EJB remote, home and bean classes) META-INF/ejb-jar.xml orion/orion-ejb-jar.xml Once you have that structure, you can use the jar program to create the EJB jar file: jar cvf myapp-ejb.jar mypackage/*.class META-INF/ejb-jar.xml orion/orion-ejb-jar.xml Copy the new myapp-ejb.jar file to the directory in which you will build the .ear file.

Orion JBuilder 4 Enterprise
I've just started testing JBuilder 4 Enterprise Edition. One of the nice things about it is the integration with the (included) Inprise Application Server. The OpenTools IDE includes hooks for integration with pretty much any application server, especially for EJB deployment. So, before I start coding the glue to join JB4E up with Orion, is anyone else already working on this (even Evermind?).

Re: Running multiple application instances with Orion
Kurt, Thank you for this article - it has been published on OrionSupport. A comment I have, is that instead of specifying a data-source for *every* entity-deployment in orion-ejb-jar.xml, you can specify a default-data-source in orion-application.xml which will automatically be used by every cmp entity in the entire application. Likewise, orion-application.xml also allows you to specify a data-sources.xml file to be used for the specific application - this allows you to separate configuration of data-sources in each applications. -Joe Walnes At 16:07 31/10/2000, Kurt Hoyt wrote: I've put together a how-to on running the same J2EE application, but with each instance using a different data source, using Orion.

josh, I am already using JBuilder4E with Orion. And deployment is a breeze. Just point Orion to the ejb-grp.jar that JBuilder creates and your are golden. Also, the EJB 2.0 support in JBuilder seams to be working fine. Just deployed a series of entity beans with 1..1, 1..*, *..1 OR dependent mapping this morning with no problem.

Question about jndi and Datasources
Hi! Is there a way to use orion as my connection manager, using jndi to perform a lookup for a Datasource, from an stand-alone app (not a client-app). I set up the following properties: java.naming.factory.initial=com.evermind.server.ApplicationClientInitialContextFactory java.naming.provider.url=ormi://myhostname/ java.naming.security.principal=username java.naming.security.credentials=password but when I try to set the initial context, I get the following: javax.naming.NamingException: META-INF/application-client.xml resource not found at com.evermind.server.ApplicationClientInitialContextFactory.getInitialContext(JAX) at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:668) at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:246) at javax.naming.InitialContext.init(InitialContext.java:222) at javax.naming.InitialContext.init(InitialContext.java:198) at com.enkamino.login.deploy.DeployLogin.init(DeployLogin.java:24) at com.enkamino.login.deploy.DeployLogin.main(DeployLogin.java:35) Thanks in advance.

Orion w/ postgresql
Hi all, I've been trying to start the orion server with postgresql but I can't get it working. What I did is as follows: 1. Copied 'postgresql.jar' driver to '/usr/local/orion/lib' directory. 2. Modified '/usr/local/orion/config/data-sources.xml' -- The modified 'data-sources.xml' follows: data-sources data-source class="com.evermind.sql.DriverManagerDataSource" name="PostGreSQL" location="jdbc/postgresql" xa-location="jdbc/xa/postgresql" ejb-location="jdbc/postgresql" connection-driver="org.postgresql.Driver" username="postgres" password="password" url="jdbc:postgresql://xxx.xxx.xxx.xxx:5432/mydb" inactivity-timeout="30" / /data-sources And the error message follows: [root@localhost orion]# java -jar orion.jar Auto-deploying addressbook (New server version detected)...

(copying from xterm and pasting to netscape). Back to our topic... I believe that I misconfigured something. When I worked on Sun's j2ee app. server, it had a similar problem. Unfortunately, postgresql doesn't seem to differentiate cases, but ejb does. Even if I create a table in upper cases in postgresql, postgresql rewrites the names of the tables in all lower cases. So what I did with Sun's j2ee, I manually changed table names and field names with all CMP beans. I greatly appreciate you time. Hapy happy Halloween. ;-P Seung
RE: Orion w/ postgresql
The first error is due to using an old postgres JDBC driver - get the latest source from CVS and compile it yourself (not too tricky to do, I figured it out!) That might clear up the second problem as well, I think it will.

Hi, You have to hack the config/database-schemas/postgresql.xml changing the null="null" to null="". This works fine.

JPS1.1 is sucessfully installed on Orion
Dear, Harrison Thank you very much my warmhearted friend. I am very happy to see JPS1.1 is sucessfully installed on Orion after I followed you instruction step by step. Thanks again. yoursUrey www.easipath.com[EMAIL PROTECTED] Ps. The message you sent to me is very helpful. I think somebody on J2EE forum would be very happy to see your message too. I sugest that you post the message on J2EE forum Enterprise Java BeansTM. * - Original Message - From: "Ray Harrison" [EMAIL PROTECTED] To: "Orion-Interest" [EMAIL PROTECTED] Sent: Tuesday, October 31, 2000 8:24 PM Subject: Re: PetStore run in Orion error,Help Me Hi Urey - Here is what Sun says about your immediate problem. Workaround #1: -- If you are only interested in the English version of the Petstore then please use following steps. Please note this option will not allow you to view the Japanese version of the Petstore. 1. change directory to jps1.1/src/petstore/src/docroot/xml 2. open the file named "requestmappings.xml". 3. delete the following line: screen-definition url="/xml/ja/screendefinitions.xml" language="ja_JP"/ 4. save the file with the line now deleted. 5. build and deploy the petstore.ear There are a number of other issues associated with this particular release of the pet store. You aren't finished yet! Go to the main source directory - on my machine it is c:\jps1.1\src\petstore\src\ and open estore-ejb.xml: Find the line securityAdapterClassName and replace the value for the j2ee security adapter with env-entry-valueOrionSecurityAdapter/env-entry-value The whole entry should look like this: env-entry env-entry-namesecurityAdapterClassName/env-entry-name env-entry-typejava.lang.String/env-entry-type env-entry-valueOrionSecurityAdapter/env-entry-value env-entry-valuetrue/env-entry-value /env-entry Next: Do the above in the ..src/docroot/WEB-INF/web.xml (i.e. replace the j2eesecurity adapter w/ OrionSecurityAdapter. Also in that same file look for the lines that look like: form-login-config form-login-pageformbasedloginscreen/form-login-page form-error-pageformbasedloginerrorscreen/form-error-page /form-login-config and replace the page names as follows: form-login-config form-login-page/login.jsp/form-login-page form-error-page/error.jsp/form-error-page /form-login-config build the application and deploy the new ear file. NEXT: The old estore-orionadapter.jar file will no longer work with the petstore (works only with version 1.0.x). Do this: 1.) Extract all of the files from the estore-orionadapter.jar and open OrionSecurityAdapter.java 2.) Replace: . . . import com.sun.estore.account.ejb.DuplicateAccountException; import java.security.*; public class OrionSecurityAdapter implements com.sun.estore.util.SecurityAdapter . . . With: . . . import com.sun.j2ee.blueprints.petstore.control.DuplicateAccountException; import java.security.*; public class OrionSecurityAdapter implements com.sun.j2ee.blueprints.petstore.util.SecurityAdapter . . . and then compile this file - then jar it up into the customerEjb.jar file that is created when you deploy the application: for instance in the directory orion\applications\petstore - I probably missed a step or so - but these are at least most of the major issues.

RE: accessing javamail provider
See enclosed mail -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Christian Sell Sent: Monday, October 30, 2000 5:04 PM To: Orion-Interest Subject: accessing javamail provider Hello, I've posted this before on orion-interest: I am using JavaMail to access a pop3 mailbox. No matter where I place the pop3.jar file (from sun, or poppers.jar) in the system, I always get a NoSuchProviderException saying thath no pop3 provider was available. I have tried the following locations for the pop3.jar: orion-install, orion-install/lib WEB-INF/lib any other path referenced through library path= in orion-application.xml The problem happens even though I am able to load classes from the jar via Class.forName(). To verify this problem further, I deployed the same application on JRun 3.0. With JRun, I have to place the jar file in jrun-install/lib/ext (actually thats where the one that comes with JRun is located), and everything works fine. thanks, Christian Sell I had the same problem with ldap.jar providerutil.jar (providers for JNDI). The problem is that due to the way Orion does its classloading mail.jar classes are loaded by an Orion classloader (via the manifest in the orion.jar) at a *lower* level than the classloader that handles orion/lib. The ways you can fix this (which are both kind of hacks IMO) are to put pop3.jar in your jre/lib/ext directory, or run orion as "java -classpath orion.jar:pop3.jar;etc com.evermind.server.ApplicationServer" To make this a little simpler I have written a shell script to include all jars in my own "lib" dir, all orion jars, etc into a CLASSPATH var, and then run Orion as above - so, you can start/stop orion w/ "orion start", "orion stop", "orion run", etc. If there is any interest I could send this script out... I think the problem is really with Orion including some of the J2EE jars as standard in the orion.jar manifest. It's a nice idea, but based on the above problem it would be easier just NOT to include them. So, to the Orion developers out there, please: 1) don't bother to include mail.jar/jndi.jar/etc (or put them in orion/lib instead of the orion.jar manifest) or 2) fix Orion classloading to work with the provider mechanisms of JavaMail and JNDI because 3) get Sun to change the provider mechanism to use different classlaoders/etc is not very likely...

JavaBean - setter methods NOT being called!
Hi! Anyoneever experienced a setXX method NOT being called on a JavaBean when using Orion = 1.3.8. Well, I have more than once.. When I write a JavaBean (or kinda) and put it in the WEB-INF/classes directory and I have a simple JSP page with the jsp:useBean and jsp:setProperty property="*" tag, and I pass the JSP page the parameters as always everything seems to be ok.. Then i suddently discover that I need yet another setXX method and I change the JavaBean and pass the JSP page the new parameter, the new setXX method is NOT being called. Like the Orion-server is still using the old "interface" of setter methods, but I can see thats it's the right bean thats being used if i for instance change some logic in one of the "old" setXX method it gets executed OK.. Strange!
